Before Zhang Xin took her daughter to the bookstore, she was taken good care of by Yan Yang. Zhang Xin's words and deeds deeply touched Yang Yan. Yang Yan experienced two unhappy marriages. She took her son alone and felt sorry for him, so she wanted to find a man who loved the child as the father. So Yang Yan started her plan, approached Zhang Yi and her work step by step, fixed Zhang Yi and Zhang Xin, and tried to force them to divorce.
But in the end, Yang Yan's true face was exposed, and her goal was not realized, because Wang Lu, the son of Yang Yan, knew that his mother had destroyed other people's families and disliked Zhang Xin very much. When Yang Yan saw this scene, he gave up Zhang Xin and returned the evidence that helped Rui Zhou to make false accounts to Zhang Xin.
